sorafenib tosylate following a liver transplant in treating patients with liver cancer

Conditions: Adult Primary Hepatocellular Carcinoma; Localized Resectable Adult Primary Liver Cancer; Localized Unresectable Adult Primary Liver Cancer; Recurrent Adult Primary Liver Cancer

Summary: the purpose of this study is to determine if sorafenib (sorafenib tosylate) is a safe and effective treatment option for preventing liver cancer in high risk patients following liver transplantation. liver transplantation is a treatment option for liver cancer patients, but despite transplantation, the liver cancer can recur in the new, transplanted liver. it is not known whether sorafenib is effective in preventing cancer recurrence in high risk patients following liver transplantation

primary objectives: i. two-year recurrence free survival (rfs). secondary objectives: i. one-year recurrence free survival. ii. overall survival (os). iii. safety. iv. impact of drug-drug interactions (i.e. immunosuppression agents). v. impact of biomarkers (alpha-fetoprotein \[afp\], protein-induced by vitamin k absence or antagonist ii \[pivka ii\]). vi. effects of therapy on wound healing. vii. impact of hepatitis c viral recurrence. outline: patients are randomized to 1 of 2 treatment arms. arm i: patients receive sorafenib tosylate orally (po) twice daily (bid). arm ii: patients receive placebo po bid. in both arms treatment continues for 24 months in the absence of disease progression or unacceptable toxicity. after completion of study treatment, patients are followed up every 6 months for 2 years.

the definition of adequate contraception will be based on the judgment of the principal investigator or a designated associate * patient must be able to swallow and retain oral medication * patient must exhibit the ability to understand and willingness to sign a written informed consent regarding the study and alternative treatments exclusion criteria: * significant ongoing immunologic rejection based on pathology and clinical diagnosis (from time of transplant until randomization) * use of t cell depleting agents for prevention or treatment of rejection at any point prior to or after enrollment in the study * patient with documented evidence of metastatic disease * 100% tumor necrosis on explant pathology * use of mammalian target of rapamycin (mtor) inhibitors prior to transplant and as post-transplant immunosuppression * use of alemtuzumab * living donor liver transplant (ldlt) or donation after cardiac death transplant (dcdt) * human immunodeficiency virus (hiv) positive patients * hepatitis c virus (hcv) recurrence at the time of randomization * use of direct acting antivirals for hcv recurrence * requirement of re-transplantation for primary non function * uncontrolled hypertension, defined as systolic blood pressure \> 140 mmhg or diastolic pressure \> 90 mmhg, despite optimal medical management * active or clinically significant cardiac disease including: * congestive heart failure - new york heart association (nyha) \> class ii * coronary artery disease * cardiac arrhythmias requiring anti-arrhythmic therapy other than beta blockers or digoxin * unstable angina or new-onset angina within 3 months before randomization, or myocardial infarction (mi) within 6 months before randomization * clinically active serious infection documented by positive cultures or an incomplete course of treatment for bacteremia or fungemia * evidence or history of bleeding diathesis or coagulopathy * patients with any pulmonary hemorrhage/bleeding event grade 2 or higher within 4 weeks before randomization * patients with thrombotic, embolic, venous, or arterial events, such as cerebrovascular accident (including transient ischemic attacks \[tias\]) within 6 months before randomization * prior use of raf-kinase inhibitors (sorafenib), vascular endothelial growth factor (vegf) inhibitors, mitogen-activated protein kinase (mapk)/extracellular-signal-related kinase (erk) kinase (mek) inhibitors, or farnesyl transferase inhibitors * patients using cytochrome p450 3a4 (cyp3a4) inducers (eg, phenytoin, carbamazepine, phenobarbital, st. john's wort dexamethasone) at a dose of greater than 16 mg daily, or rifampin and/or rifabutin within 28 days before randomization * patients with non-hcc malignancy except those with dcis (ductal carcinoma in situ), cervical cancer in-situ, basal cell or superficial bladder tumor; patients surviving a cancer that was curatively treated and without evidence of recurrence for more than 3 years before randomization are allowed * presence of a non-healing wound, non-healing ulcer, or bone fracture * known or suspected allergy or hypersensitivity to any of the study drugs, study drug classes, or excipients of the formulations given during the course of this trial * any malabsorption condition * women who are pregnant or breast-feeding * inability to comply with the protocol and/or not willing or not available for follow-up assessments * patients with fibrolamellar hcc, cholangiocarcinoma, and combined hcc-cholangiocarcinoma * any condition which, in the investigator's opinion, makes the patient unsuitable for trial participation * prior use of any systemic chemotherapy for hcc * prior use of systemic investigational agents for hcc * prior use of raf-kinase inhibitors (sorafenib), vegf inhibitors, mek inhibitors or farnesyl transferase inhibitors * use of biologic response modifiers, such as granulocyte colony-stimulating factor (g-csf), will not be permitted within 3 weeks prior to study entry;
